This show has been commercially released as "Dick's Picks Vol. 4" and/or "Bear's Choice"
Recorded by PBS at the Family Dog on 02-04-70 and originally broadcast on 12-13-70 for a television documentary entitled, "San Francisco Rock: A Night At The Family Dog" filmed at the Family Dog on 02-04-70. The China > Rider has been matched with this date but the rest of the setlist does not match either Deadbase or Deadlists which also lists a 06:26 Hard to Handle prior to China > Rider and notes that sets were also performed by the Jefferson Airplane and Santana. The St. Stephen > NFA > St. Stephen > Midnight Hour following China > Rider is continuous with the China > Rider in terms of the source quality, crowd and overall musical feel. Accordingly, it appears that this is all one set.
Hard to Handle and the "All Star Jam" included here and sourced from the PBS TV broadcast were missing from the previously circulating tape.
There has been some confusion about this tape where it was initially labeled as 08-30-70, which was a KQED broadcast called Calibration. This is a well-documented show though, and the set list is completely different from the one above.
